remove the plastic covers and see which seal is leaking top cam shaft seal
or the lower pully seal both times the timing belt has to come off
as post above
the plastic covers had 7 screws may be 8 or 10 mm small socket was required to take them off
Still remove the tyre and the splash guard in the mudguard to get a better look at the bottom seal ok hope that helps
I was hoping it would just be the tappet cover leaking
